Hi there!
It would be a pleasure to me helping you out in that case.
Just mail that "README" to "shadowbyte at everymail.net". (Recognize that "at" it will confuse any spiders running through this page )

two trials will be better than one
i could do it too, for making it secure, and training my english a little
if you want, readme goes to iunknown at walkshome.de, i'll try to get it managed as soon as possible._________________geek by nature, linux by choice

A common problem, if you have just a single analog telephon line: if you have a PPP connection, you are unreachable with telephone. Activating the Telekoms knockingtone is not enough: the time till your modem hangs up is to long. And V92-Modems are unsupported by the providers yet.

I (the author) wrote a program to solve this problem. Line-Out of your modem will be connected with Line-In of your soundcard. The program analyzes the audio-signal on existing ppp connection. If it detects the knockingtone, ppp connection will be quited, so you can reply the call.

The program ist written for Linux only, for Windows you need to adjust capability to read from the soundcard.

Actuall version will work with V90-Modems to (but not the old version of November 2001). The difference between V90-Modems and former ones is: the volume is different over the frequency. You need to adjust the algorithm.

-You need a cable from Line-Out of the modem to the Line-In of your Soundcard.
The mass-connection shouldnt be diverted, so you could get this loop-sound. (Complicated german, this is the sound you probably know if you have a tv tuner in your box, you get this disturbing sound.)
-In /etc/chatscripts/... you need to make the modem to produce some sounds (there should be some options for this)
-To select the knockingtone of the telekom, call 43#.

The program reads from /dev/dsp. (Here he describes the algorithm his program uses, if you need this, mail me again.) If the tone is found, the ppp connection gets interupted.

Every 20 secs, the program controlls if a audio signal comes from the modem.

The scripts poff-bei-anklopfton-* (means poff-on-tone or something) can be used for automatic Start and Stop of the program. At least in Debian it works, if placed in /etc/ppp/ip-up.d/ and ../ip-down.d/. (execute make install as root). You need to adjust you settings for soundcards and devices, default is a second soundcard.

The program protokols to syslog.

For debugging, detekt can be called with two options:
-c for continue: theres no program end after detecting the tone.
-o for output: Outputs the calculated variables. You can watch timelines with octave and the script auswert.m.

Any comments and critics, also with code go to (ernst.kloppenburg at gmx.de).

Installation (see makefile)
make detekt;
Adjust devices in poff-bei-anklopfen-*
as root: make install

and here we go, i post it, because my mail system still doesnt work on linux
hope it helps, my english is not the best, and its a 1to1-translation, i dont know what the program does exactly but you should, i think. gl_________________geek by nature, linux by choice
